18 Months on from its early access release the game is still being developed with features being added regularly. In Particular internet rocket scientists who want to clone real world designs find the procedural design mechanic - including simulation of rocket engines - a superior alternative to other games. It also includes a visual automation system called 'Vizzy' that lets designers code write software to fly their rockets instead of trusting their pilot skills. It also supports iPads and other tablets (in theory it supports phones, but the UI is hard to use at these scales). So, there's a lot to recommend it, but having said that it still lacks a lot when compared to Kerbal Space Program or Orbiter 2016, but there's an audience out there who want to build their own rockets and get turned off by little green men, and this might be perfect for them.

SpaceX has released a ground view of the stage separation of their Falcon 9 rocket during the CRS-20 launch on March 7, 2020.

Some of the smallest and lightest rockets in NASA’s lineup have made some of the biggest impacts on science. With a flight time of just about 15 minutes before falling back to Earth, sounding rockets collect unique observations on everything from our planet’s atmosphere to the Sun and even distant galaxies. Join us live to hear from scientists who have traveled to the ends of the Earth to launch sounding rockets, flown cutting-edge instruments on these suborbital flights, and used sounding rockets to make brand-new scientific discoveries.

Mark Thomas (CEO - Reaction Engines) and Adam Dissel (President - Reaction Engines Inc.) talk about the achievement of reaching Mach 5 Tue, 2019-10-22 07:14 Reaction Engines has successfully tested its innovative precoolerat airflow temperature conditions representing Mach 5, or five times the speed of sound, marking a significant milestone in the development of its SABRE™ engine and paving the way for a revolution in hypersonic flight and space access. The precooler heat exchanger is a vital component of Reaction Engines’ revolutionary SABRE air-breathing rocket engine and is an enabling technology for other precooled propulsion systems and a range of commercial applications. This ground-based test achieved the highest temperature objective of the Company’s HTX testing programme and took place at its specially constructed unique facility at the Colorado Air and Space Port, United States. During the latest series of tests, Reaction Engines’ unique precooler successfully quenched airflow temperatures in excess of 1,000°C (~1,800°F) in less than 1/20th of a second. The tests demonstrated the precooler’s ability to successfully cool airflow at speeds significantly in excess of the operational limit of any jet-engine powered aircraft in history. Mach 5 is more than twice as fast as the cruising speed of Concorde and over 50% faster than the SR-71 Blackbird aircraft – the world’s fastest jet-engine powered aircraft. This most recent test builds upon the success of previous HTX hot tests undertaken in April which saw the precooler successfully operate at temperatures of 420ᵒC (~788ᵒF) – matching the thermal conditions corresponding to Mach 3.3 flight. Commenting, Mark Thomas, Chief Executive, Reaction Engines, said: “This is a major moment in the development of a breakthrough aerospace technology which has seen Reaction Engines’ precooler tested at Mach 5 airflow temperature conditions, smashing through previous achievements at Mach 3.3 temperatures and paving the way for hypersonic flight. In addition to its use in our SABRE class of air breathing rocket engines, there are numerous exciting commercial applications for our precooler technology, which delivers world-leading heat transfer capabilities at low weight and compact size, and we are seeing significant interest from a range of potential customers and technology partners.” Reaction Engines’ patented precooler heat exchanger has the potential to be used in a wide range of commercial thermal management applications. These include the development of precooled systems that would significantly enhance the performance of existing jet engine technology, along with applications in automotive, aerospace, energy and industrial processes. The major testing milestone is the culmination of 30 years of engineering innovation since Reaction Engines was founded in 1989 by three propulsion engineers from Rolls-Royce, Alan Bond, Richard Varvill and John Scott-Scott. Richard Varvill, Reaction Engines’ co-founder and current Chief Technology Officer, said: “This is a momentous landmark for Reaction Engines in the development of its SABRE engine, which has the potential to revolutionise both access to space and high-speed flight by powering aircraft to five times the speed of sound. The performance of our proprietary precooler technology was validated at hypersonic flight conditions and takes us closer to realising our objective of developing the first air-breathing engine capable of accelerating from zero to Mach 5.” The HTX hot heat exchanger testing programme is a significant milestone on the roadmap to enabling transformational SABRE powered space access systems and has been keenly supported by the UK Space Agency (UKSA) and European Space Agency (ESA). In March, the two agencies reviewed and validated the preliminary design of the demonstrator engine core of SABRE, which Reaction Engines will use to undertake ground-based testing at its under-construction TF1 test facility at Westcott, Buckinghamshire, UK. The HTX hot heat exchanger test programme was supported under a contract to the Company’s US subsidiary Reaction Engines Inc. by the Defense Advanced Research Projects Agency (DARPA). The precooler test item was designed and constructed at Reaction Engines’ headquarters in the UK, before being shipped to the Company’s Colorado site for testing. Following this significant testing milestone, the Company will embark on achieving the next steps of the SABRE programme while also pursuing nearer-term opportunities that will benefit from the addition of the Company’s heat exchanger technology. Over the last four years Reaction Engines has raised over £100m from public and private sources and has secured investment from BAE Systems, Rolls-Royce and Boeing HorizonX. https://www.reactionengines.co.uk/news/reaction-engines-test-programme-fully-validates-precooler-hypersonic-heat-conditions

Even as the first rockets were launched into space decades ago, aerospace knew it was a wasteful process. Rocket stages, motors, and complex equipment crashed into the ocean or burned up in the Earth’s atmosphere. Could spaceplanes bring the costs down? Flying to orbit with a combination of jet engines and rockets and then safely re-enter the Earth’s atmosphere again. Single-stage to orbit spacecraft and spaceplanes have always seemed out of reach, and actually not that practical. But what about a two-stage, fully reusable spaceplane? Exodus Space Corporation has been secretly working on this concept for a decade now, and what they’re proposing is pretty revolutionary.

On Saturday, September 28th, SpaceX CEO Elon Musk stood in front of an audience in Boca Chica, Texas, and presented the fully assembled SpaceX Starship, 50 meters tall and made from shiny stainless steel. As part of his presentation, Musk showed off the history of the company’s developments so far and gave us an updated view of what Starship and its first stage Superheavy booster will look like when they’re fully operational. It was actually a pretty short presentation, and there weren’t a lot of details. But he stuck around to answer questions from many space journalists, and we’ve got a much better idea about Starship and what happens next.

The Goal of Von Braun Station is to build a dual-use station that is economically self-sustaining. Von Braun Station creation will also form a space construction industry with bots, pods, drones, construction arms, new space suits, and large-scale truss building machines designed for building large structures in space. This video, and the ones that will follow, were made for NASA and other aerospace engineers to see that this is a technically feasible design, with a solid business plan, that will allow NASA and other space agencies to buy, rent, or lease space on this station very affordably. Later, when they have acquired the low-gravity data they need, they can move on to other projects with no binding financial ties. We ask you all the same two questions: 1. Is this a good design? 2. Is it the right time right to build a rotating station to acquire valuable, low-gravity, human physiology data? Thank you for your time and consideration.

It’s amazing to think there are telescopes up in space, right now, directing their gaze at distant objects for hours, days and even weeks. Providing a point of view so stable and accurate that we can learn details about galaxies, exoplanets and more. And then, when the time is up, the spacecraft can shift its gaze in another direction. All without the use of fuel. It’s all thanks to the technology of reaction wheels and gyroscopes. Let’s talk about how they work, how they’re different, and how their failure has ended missions in the past. 06:49 Scientists May Have Figure Out Why So Many Spacecraft Were Failing - https://www.youtube.com/watch?v=KibT-PEMHUU Our Book is out! https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/ Audio Podcast version: ITunes: https://itunes.apple.com/us/podcast/universe-today-guide-to-space-audio/id794058155?mt=2 RSS: https://www.universetoday.com/audio What Fraser's Watching Playlist: https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1G Weekly email newsletter: https://www.universetoday.com/newsletter Weekly Space Hangout: https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/ Astronomy Cast: https://www.youtube.com/channel/UCUHI67dh9jEO2rvK--MdCSg Support us at: http://www.patreon.com/universetoday More stories at: http://www.universetoday.com/ Twitch: https://twitch.tv/fcain Follow us on Twitter: @universetoday Like us on Facebook: https://www.facebook.com/universetoday Instagram - https://instagram.com/universetoday Team: Fraser Cain - @fcain / [email protected] Karla Thompson - @karlaii / https://www.youtube.com/channel/UCEItkORQYd4Wf0TpgYI_1fw Chad Weber - [email protected] References: https://www.nature.com/news/the-wheels-come-off-kepler-1.13032 http://www.planetary.org/blogs/jason-davis/lightsail-2-successful-flight-by-light.html https://astrobites.org/2013/05/21/kepler-reaction-wheel-failure-cripples-spacecraft-but-mission-thrives/ https://www.nasa.gov/mission_pages/dawn/news/dawn20120418.html https://www.jpl.nasa.gov/blog/2016/1/dawns-sunny-side-views-of-dwarf-planet-ceres/#RWAs https://www.youtube.com/watch?v=KibT-PEMHUU https://www.spacetelescope.org/announcements/ann1818/ https://jwst.nasa.gov/content/forScientists/faqScientists.html#wheels https://www.youtube.com/watch?v=DFmOr1vMOT4

A scale model of the X-59 QueSST, NASA’s supersonic X-plane, recently completed a test at NASA Glenn’s 8-foot by 6-foot supersonic wind tunnel. This test was used to verify the performance of the aircraft’s unique top-mounted engine through various flight conditions, from takeoff to nearly one and half times the speed of sound (Mach 1.4). The tests were successful in demonstrating the X-59’s engine will perform as expected when it begins initial flight testing in 2021.
